Halloween, or All Hallows’ Eve, has a tradition stretching back to the 15th century and earlier, though it is currently a more secular holiday, with children and the young at heart dressing up as everything from scary ghouls and monsters to the more tame video game characters or that bane of every feminist out there, the “sexy” nurse/librarian/pikachu/what have you.

Regardless of how you celebrate, though, we thought you’d enjoy this list of the scariest Mac games we could think of, each available to play on current (and some older) Macs just in time for the next couple of creepy weeks.
